Article in Nature Materials


Associates of the Department of Condensed Matter Physics Tina Arh, Matej Pregelj, pHD, and prof. Andrej Zorko pHD, discovered the first realization of a quantum spin liquid on a Ising triangular-lattice antiferromagnet. They performed a large scale experimental study in collaboration with the researchers from the Slovenian Institute of Mathematics, Physics and Mechanics as well as researchers from India, Great Britain, France and the USA. The results were published in Nature Materials in the article External link opens in new tab or windowThe Ising triangular-lattice antiferromagnet neodymium heptatantalate as a quantum spin liquid candidate. In addition to being a significant scientific discovery, this discovery also has an important potential for the latest quantum technologies, as spin liquids are seen as one of the most perspective platforms in quantum computing.
